Terrien's Marginal Degeneration Treatment in Laguna Woods, California

Medically reviewed by Dr. Alexander Bonakdar, O.D. · Updated April 2026

Terrien's marginal degeneration is a rare, slowly progressive, non-inflammatory thinning of the peripheral cornea, typically starting superiorly. It causes increasing against-the-rule astigmatism as the thinning progresses, making vision correction with standard glasses increasingly difficult. The peripheral thinning can eventually threaten corneal integrity. Scleral lenses are effective for vision correction, and Pentacam tomography is used to monitor progression.

For Laguna Woods's mature residents, terrien's marginal degeneration management takes into account age-related changes, current medications, and overall health goals to create a practical, effective treatment plan.
